Title: Mortise lock or box lock for sound-insulating doors
Inventor: SCHUBERT ROLF DIPL ING
IPC: E05B17/00
Filed: 1989-03-16
Abstract: The invention relates to a mortise lock or box lock for sound-insulating doors with a door catch which can be drawn into the lock box for unlocking by means of a door handle, and with a device which can be activated, by turning the door handle counter to the unlocking direction, for pressing the door leaf against the door frame. The device has a wedge which can be moved by bearing against a counter-piece which slides on a surface of the wedge and is preferably connected via a closure plate to the door frame. The object of the invention is to improve known locks of this kind. According to the invention, this object is achieved by providing, in addition to the door catch, a bolt which is designed in a wedge shape at one end and has a wedge surface which can bear against the counter-piece, and a drive mechanism which converts the rotational movement of the door handle into a translational movement for displacing the lock. By means of the invention, the force expended on pressing the door leaf against the door frame is reduced.

Inventor: SHIBATA KATSUHIRO
IPC: F16D65/092
Filed: 1989-05-31
Abstract: The friction pad for use with a disc brake has a central main portion (1) and a peripheral portion (2, 2') which are formed of different matrices having different compositions. The matrix of the central main portion (1) contains a hard substance or substances having a specified range of hardness whereas the matrix of the peripheral portion (2, 2') does not contain such hard substances or contains them in only a limited smaller amount than the central main portion (1). This prevents the brake disc from wearing due to friction with the pad and thus avoids uneven abrasion of the brake disc. The matrices may include fibres of steel, alumina, glass, or aramid. <IMAGE>
